RBI Basel III disclosures: New quarterly rules by 2026

What the RBI has proposed

The Reserve Bank of India (RBI) has proposed a revised disclosure framework for banks under Basel III norms, tightening what lenders must publish on their financial strength and risk profile. The draft focuses on Pillar 3 disclosures, which are designed to improve transparency and market discipline by making comparable prudential data available to investors and other stakeholders. The RBI said banks would need to disclose more granular information on capital adequacy, leverage, liquidity and risk exposure. A key change is the move to quarterly disclosures in a uniform format.

Quarterly templates for key prudential metrics

Under the draft circular, banks will have to provide quarterly disclosures covering a standard set of indicators. The RBI listed Common Equity Tier 1 (CET1) capital, total capital, risk-weighted assets (RWAs), leverage ratio, liquidity coverage ratio (LCR) and net stable funding ratio (NSFR) among the core metrics. The intent is to bring consistency in what is disclosed and how it is presented. By requiring a uniform format, the regulator is aiming to make it easier for market participants to compare banks on capital buffers, liquidity position and risk taking.

Explanations for quarter-on-quarter movements

The RBI has also proposed that banks should explain significant changes in the disclosed metrics compared with previous quarters. This includes describing key drivers behind such movements rather than just presenting numbers. The draft framework extends beyond capital and liquidity ratios to require descriptions of a bank’s main activities and all significant risks, supported by relevant data. If risk exposures change materially between reporting periods, banks should describe those changes and management’s response.

Qualitative and quantitative risk disclosures

The proposed framework expects banks to provide sufficient information, in both qualitative and quantitative terms, on how they identify, measure and manage risks. The RBI’s draft calls for disclosures that describe significant risks and the underlying data that support those disclosures. It also points to the need for banks to explain risk management processes and procedures. The emphasis is on making Pillar 3 reports more decision-useful, especially when risk exposures or key ratios shift.

Website hosting, archives, and publication timing

A notable operational requirement in the draft is the creation of a dedicated online repository. Banks would be required to maintain a ‘Regulatory Disclosure Section’ on their websites where all disclosure information is made available to market participants. Banks would also need to host an archive of Pillar 3 reports for at least ten years.

On timing, the RBI said a bank must publish Pillar 3 disclosures concurrently with its financial reports for the corresponding period. If a Pillar 3 disclosure is required for a period when a bank does not produce any financial report, the disclosure should be published as soon as practicable.

Limited exceptions, with explanations

While the draft tightens disclosure expectations, it also includes exceptions. If a bank believes the information requested in a template or table would not be meaningful to users, it may choose not to disclose part or all of that information. The RBI gave an example where exposures and RWA amounts are deemed immaterial. However, the bank would have to explain through narrative commentary why it considers the omitted information not meaningful.

Consultation window and implementation date

The RBI has invited comments on the draft circular by June 2. It also said the final directions would come into effect from the quarter ended September 30, 2026. This provides banks time to align internal reporting systems, controls, and website publication workflows with the proposed quarterly cadence and standard templates.

How this fits into other RBI capital and disclosure changes

The draft Pillar 3 framework comes alongside other recent RBI actions on capital and disclosures mentioned in the provided material. The RBI has revised guidelines related to the inclusion of quarterly profits in banks’ core capital calculations by removing an earlier condition linked to provisioning for non-performing assets (NPAs). Under the earlier framework, commercial banks, excluding local area banks and regional rural banks, could include quarterly profits in CRAR calculations only if incremental NPA provisions in any quarter did not deviate by more than 25 percent from the average provisions across all four quarters. The RBI said the revised framework removes this qualifying condition.

Separately, the material also notes draft amendments for Local Area Banks that align disclosure requirements with updated investment portfolio guidelines, including a clarified definition of “Revenue Reserve” and a structured disclosure format for movement of provisions relating to non-performing investments (NPIs). It also references a revised granular reporting format for “Exposure to Capital Markets” under Notes to Accounts, with those changes to come into effect from July 1, 2026 or earlier upon adoption by banks.

Market impact: what changes for investors and banks

From a market transparency standpoint, quarterly, standardised Pillar 3 disclosures can increase the amount of comparable data available on capital strength, leverage and liquidity. The requirement to explain significant movements and their drivers can also improve context around quarter-to-quarter changes in ratios like CET1, LCR, NSFR and leverage.

For banks, the practical impact is likely to be operational. The draft creates clear expectations around data completeness, presentation formats, website hosting, and long retention of disclosure archives. It also links disclosure timing to financial reporting timelines, which can require coordination across finance, risk, compliance and investor relations functions.

Key points at a glance

Why the proposal matters

Pillar 3 disclosures are one of the main channels through which banks communicate risk and resilience to the market. By specifying quarterly frequency, standard templates, and narratives for major movements, the RBI is pushing for disclosures that are not only more frequent but also easier to compare across lenders. The inclusion of website archiving and concurrent publication with financial reports also signals a push toward consistent availability of regulatory information over time.

Conclusion

The RBI’s draft Pillar 3 circular raises the bar on how banks disclose capital, leverage, liquidity and risk information, and it sets a clear implementation timeline ending with the September 2026 quarter. With comments open until June 2, the next milestone is the release of final directions, after which banks will need to operationalise quarterly templates, website disclosures and long-period archiving requirements.
